Exponents on the SAT
When taking the SAT, You are bound to encounter questions related to exponents. This is a topic that the SAT frequently tests, and there are specific rules that you need to be familiar with. The two rules that the SAT loves to include are the power rule and the fraction power rule. Understanding and applying these rules will help you simplify expressions and solve problems involving exponents more efficiently.
The power rule states that when you have a variable raised to a certain power, and that variable is raised to another power, you can simplify the expression by multiplying the exponents. For example, if you have K to the 5/16 raised to the 16th power, the exponent becomes 5.
The fraction power rule, on the other HAND, states that a variable raised to a fractional exponent is equivalent to the same variable raised to the nth root of the numerator, where n is the denominator. For instance, K to the 5/4 is the same as the fourth root of K to the 5.
By mastering these rules, you will be well-prepared to tackle any exponent-related questions that come your way on the SAT. Practice applying these rules to various expressions and problems to improve your score in this area.
Pros:
- Mastering exponents will allow you to simplify expressions more efficiently.

Probability Tables and Conditional Probability
Another topic that frequently appears on the SAT is probability, particularly probability tables with conditional probability. These types of questions require a two-step approach. First, you need to identify the condition given in the problem, which will eliminate certain parts of the probability table. Second, you need to determine what you're looking for Based on the remaining portion of the table.
For example, a question might ask, "What is the probability of selecting a participant from group A given that the participant is at least 10 years of age?" In this case, you need to find the probability of selecting a participant from group A out of the remaining participants after applying the given condition.
To calculate the probability, you divide the number of favorable outcomes (participants from group A) by the total number of possible outcomes (participants in the remaining portion of the table). Simplifying the fraction, you can determine the correct answer.
Understanding probability tables and conditional probability will allow you to approach these questions systematically and find the correct solutions.

Exponential Growth
Exponential growth is another concept that you can expect to encounter on the SAT. It involves a function that increases at an increasing rate over time. The SAT might present you with a Scenario or problem where you need to analyze the growth of a population, investment, or other quantities.
To calculate exponential growth, you can use the formula A = P * (1 + r)^t, where A represents the final amount or value, P is the initial amount or value, r is the growth rate as a decimal, and t is the time in years.
For example, suppose a model estimates that at the end of each year from 2017 to 2023, the number of mice in a population was 125% more than the previous year. If there were 450 mice in the population at the end of 2017, you can use the formula to determine the equation representing this model.

Finding the Slope of a Tangent Line to a Circle
The SAT occasionally presents questions involving circles and tangents. In these questions, you may be required to find the slope of a line that is tangent to a circle.
To find the slope of a line tangent to a circle, you need to understand that the line is perpendicular to the line connecting the center of the circle to the point of tangency. By determining the slope of the line connecting these two points, you can find the perpendicular slope.
For example, if you are given a circle with its center at (-3, 4) and a point of tangency at (-2, 1), you can calculate the slope by using the formula (y2 - y1) / (x2 - x1). In this case, the slope would be 3/4.
Understanding this concept will help you confidently approach questions that involve tangents to circles on the SAT.
